The research found that global warming, which is warming the planet’s Arctic regions, will eventually lead to melting sea ice in that part of the world. Fresh, cold water mixes with warmer currents that pass seasonally across the North Atlantic before returning south. Melting water will cool warm currents, disrupting cycles that have been established over thousands of years. Just as warming of the oceans due to El Niño causes warming of the atmosphere, cooling will lead to a decrease in the temperature of the atmosphere in the regions along the path of these currents.Channel 24 writes, citing a study published in the journal Nature Communications.

Such a conclusion was not reached overnight. Scientists discovered this in the distant past Increased freshwater flows from melting Arctic sea ice significantly affected ocean circulation, causing temperatures to drop in Northern Europe, so this could happen again.

The Arctic Ocean is expected to experience ice-free summer conditions by 2050. Also earlier this month, dozens of climate scientists warned in an open letter that climate change poses a major “risk of a serious change in ocean circulation in the Atlantic, which will lead to devastating and irreversible consequences.”

The research team, by scientist Mohammed Ezat from the iC3 Center for Polar Research, used a combination of biological, inorganic and organic geochemical markers from sedimentary rock cores taken from the northern seas. These cores act as time capsules that store information about past ocean conditions. By analyzing chemical signatures in these sediments, the team was able to reconstruct past temperatures and salinity levels of the sea surface, freshwater resources, and the formation processes of deep-sea waters.

Thus, warming of the climate and increased melting of Arctic sea ice in that distant period We managed to connect with cooling in Europechanges in regional sea surface temperature and disturbances in the circulation of ocean currents. As it turns out, melting sea ice changed the salinity and density of water and disrupted the normal flow of currentsThis led to changes in the circulation patterns and distribution of heat in the ocean.

Study of past climate The key to understanding our sad futurescientists are sure of this. The scientist explains that it is very important to study the dynamics of the last interglacial period. Past warm periods in Earth history highlight the importance of feedback mechanisms in the climate system. As the Arctic continues to warm and sea ice shrinks, further changes in ocean currents and weather patterns may occur.
